1 Claim.

This invention relates to a new and useful improvement in rail greasersand has for its object the construction of a greasing device forelevator guide rails which is simple in construction and entirelyautomatic in operation.

A principal object of the invention is to provide a rail greasing devicewhich will automatically feed grease to the guide rail as required.This, and other objects of the invention, are accomplished by providinga hollow housing having a closed top and open bottom, a front wallhaving a forwardly extending portion provided with a slot the fulllength thereof for receiving the guide rail, a plunger entered in andclosing said opening and a base for said plunger.

For a full understanding of my invention, and

the manner in which the same is constructed and operated, reference isto be had to the following description and the accompanying drawing inwhich:

Figure 1 is a side elevation of my invention partly in cross section.

Figure 2 is a top plan view.

Figure 3 is a side elevation of the plunger and base.

Figure 4 is an alternative view of the base attached to the closed endof the housing.

Like characters of reference refer to like parts throughout thespecification and drawing.

The preferred embodiment of my invention 11- lustrated in the drawingcomprises, a rectangular grease containing housing having front and rearwalls and side walls, I, 2, 3 and 4 respectively, the top of the housingbeing closed and the bottom open. The upper end of the front wall isextended outwardly as indicated at 1 and this forward extension isprovided with a vertical, central slot 8 for receiving the face andsides of the rail 9. The slot 8 should be of such a size as to permitonly a slight clearance of the sides and face of the rail.

The side walls of the forwardly extending por tion I are curved towardthe slot 8 for the purpose of forcing the grease onto the side of therail. The top side of the housing is formed so that it slopes upwardlyfrom the back to the top front edge of the housing for the purpose offorcing grease towards the said slot. A plunger I0 which is enterableinto the housing is mounted on a fixed base II, the base being providedand formed with slots l2 to provide adjustable means for attaching thebase to the top of the elevator shoe which is indicated at IS. The sizeof the plunger It) should be such that it will enter the housing so thatthere will be no binding as between the interior walls of. the housingand the sides of the plunger.

In operation, as indicated in the drawing, the base is mounted on thetop of the elevator, or counterbalanced shoes, as already noted, and astick of grease placed either on the top of the plunger or in thehousing.

The housing is mounted on the plunger and the weight of the same forcesthe grease to and through the slot 8 by means of which it is spread ontothe sides and face of the rail 9.

The principal advantage of my invention is that when the elevator istravelling upwards, the downward pressure of the housing on the greasetherein will be increased, thereby respectively greasing the sides andface of the rail. A further advantage is that when the elevator car istravelling downwardly, very little grease is applied except at the pointwhere the elevator stops. At the point where the elevator stops, aliberal application ofv grease is effected to replenish the greaseremoved in the stopping. It will be noted from'the foregoing that therail greaser which is the subject matter of this application is entirelyautomatic in operation and thereby the grease in the housing iscontinually moved towards and through the slot 8 as it is used by theelevator guide rail. It will also be noted that when a car is travellingupwardly if there are any spots on the rail which cause friction, thefriction will force the housing downwardly to cause more grease to beforced onto the rail.

It will be apparent that modifications may be made in the preferredembodiment of my invention described herein such as reversing the deviceand having the hollow housing fixed to the base and the grease forcedthrough the slot 8 by the action of the plunger, the weight of whichforces the grease through that slot. This modification is illustrated inFigure 4 in which is shown a type of base suitable for securing theclosed end of the housing to the elevator shoe.

These and other modifications may be made without departing from thescope of the appended claim.

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent is:

A rail greaser comprising a fixed plunger, a hollow housing having aclosed top mounted on said plunger and vertically movable with respectthereto and a slot in the side of said housing for receiving a guiderail, the weight of said housing and the friction between it and saidguide rail co-operating to force grease through said slot.
